Chasing the murderer into the ancient temple, a thousand years passed in a blink of an eye. Shen Wei, the capable criminal police captain, went deep into the ancient temple on the barren mountain in order to hunt down the serial killer "The Butcher". Shen Wei accidentally traveled through time and became a concubine in the ancient harem, and the murderer became an ancient magistrate, and continued to use modern means to create unsolved cases. The palace is as deep as an abyss, surrounded by powerful enemies. While Shen Wei used her wits to deal with the Queen's concubine's overt and covert attacks, and at the same time relied on criminal investigation skills that transcended the times, she helped Xie Lin track down the "butcher" either overtly or covertly while solving the mysterious case in the palace. She and the upright Xie Lin developed a tacit understanding and affection during the life and death investigation, and the unpredictable emperor Xiao Heng's exploration and protection of her became increasingly complicated. The emotions of the three parties walk dangerously on the tightrope between conspiracy and truth.
